Brian King, Texas Instruments EDN In isolated power supplies, optocouplers pass the feedback signal across the isolation boundary. Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through the LED results ...

Steve Taranovich EDN When EDN published its first issue in 1956, electrical measuring instruments looked a little different than they do today. Howard Skolnik, a former colleague and key analog mentor from my Burr-Brown days, has always had a ...

Thomas Kugelstadt, Intersil EDN Isolation is a means of preventing current flow between two communicating points, while allowing data and power signal transmission between them. Isolation prevents high voltages from damaging sensitive electronic ...

Bob Sheehan Electronic Design Ascertaining the relationship between bandwidth and response in power supplies isn’t easy, but this Idea for Design presents a measurement approach that helps ease the process. It’s normal to assume that ...

Michael Gambuzza Electronic Design To transfer maximum power from a circuit to a load, the load’s resistance, R L , must match the source resistance, R O (Fig. 1). In the case of a complex load, Z L , and a resistive source, this transfer can ...

Maria Guerra Electronic Design Co-founder Massimo Banzi was in New York City for the, and he stopped by Electronic Design’s office to talk about the future of Arduino Arduino, an open-source electronic platform for fast prototyping, helps ...

Beebom The Raspberry Pi and Pi 2 have taken the world by storm and created a huge interest in single-board computers; their simplicity, portability, and affordability make them great for thinkerers and kids alike. But not everyone wants a Pi. If ...

Beebom Part 1 6. MinnowBoard MAX ($145) There are actually two versions of the MinnowBoard MAX available; a $140 version and a $100 version. The extra $40 gets you 2 GB of RAM instead of 1 GB, but both versions include a 1.33 GHz dual-core ...

Raymond Ho Electronic Design Most function generators and network analyzers have one port to provide the output signal. If a differential signal is needed, then you may need to acquire a network analyzer with two output ports at great cost. Of ...
